Eduard van Valkenburg fd4e6e816c Unify Azure credential handling across all Python packages (#4088 )

Replace ad_token, ad_token_provider, and get_entra_auth_token with a
unified credential parameter across all Azure-related packages.

Core changes:
- Add AzureCredentialTypes (TokenCredential | AsyncTokenCredential) and
  AzureTokenProvider (Callable[[], str | Awaitable[str]]) type aliases
- Add resolve_credential_to_token_provider() using azure.identity's
  get_bearer_token_provider for automatic token caching/refresh
- Update AzureOpenAIChatClient, AzureOpenAIResponsesClient, and
  AzureOpenAIAssistantsClient to accept credential: AzureCredentialTypes |
  AzureTokenProvider
- Remove ad_token, ad_token_provider params and get_entra_auth_token helpers

Package updates:
- azure-ai: Accept AzureCredentialTypes on AzureAIClient,
  AzureAIAgentClient, AzureAIProjectAgentProvider, AzureAIAgentsProvider
- azure-ai-search: Accept AzureCredentialTypes on
  AzureAISearchContextProvider
- purview: Accept AzureCredentialTypes | AzureTokenProvider on
  PurviewClient, PurviewPolicyMiddleware, PurviewChatPolicyMiddleware

Fixes #3449
Fixes #3500

Get Started with Microsoft Agent Framework Azure AI Search

Please install this package via pip:

pip install agent-framework-azure-ai-search --pre

Azure AI Search Integration

The Azure AI Search integration provides context providers for RAG (Retrieval Augmented Generation) capabilities with two modes:

Semantic Mode: Fast hybrid search (vector + keyword) with semantic ranking
Agentic Mode: Multi-hop reasoning using Knowledge Bases for complex queries

Basic Usage Example

See the Azure AI Search context provider examples which demonstrate:

Semantic search with hybrid (vector + keyword) queries
Agentic mode with Knowledge Bases for complex multi-hop reasoning
Environment variable configuration with Settings class
API key and managed identity authentication
